The result is the sharpest and most accurate vision you can get for your game. So you'll see the angles and lines with greater sharpness and accuracy than you will with any other non prescription pair of sunglasses. NEOX lenses provide 100 percent protection from the harmful effects of UVAUVB radiation.
